STUDY OF VLF CORONA
Abstract
A few experiments were made in the VLF range using 2 conductors under dry and wet conditions and with the conductor surfaces both normal and roughened. For the dry conductors, corona appeared at about 25 and 48 kv, respectively, for No. 16 solid, tinned copper wire and for 7-strand No. 14 copperclad steel wire. Extension to the VLF range of existent formulas for computing corona voltage at power frequencies led to values in reasonable agreement with experimental results. Formulas for predicting the effects of roughness and wetness overestimated the effects. Variation of frequency within the VLF range appeared to have no effect on the corona-incidence voltage.
